This doesn't make sense. When I first submitted it to coolsnowwolf/lede
in 2022, I used "rgmii-id" as the phy-mode, and it worked:
https://github.com/coolsnowwolf/lede/blob/master/target/linux/rockchip/files/arch/arm64/boot/dts/rockchip/rk3568-opc-h68k.dts#L24

Are you experiencing issues with both eth0 and eth1 or just one of them?
Are you using the generic-rk3568 target for U-Boot?

I can't reproduce your problem in my test.
